"From the initial interaction through sweeping up - the insulation inc team were thorough in explaining their bid, the cellulose insulation product- and the process. They showed up on time - blew our garage attic and left the garage clean."

"Exactly as the same as the first time I air sealed my attic in my previous house. Last year when we decided to sell our house I was inspecting my house as I would have if I was purchasing it. I noticed a small (1/4") gap between the master bathroom vent fan grill and the ceiling. I could not adjust it. Upon further inspection I realize it was because the foam that was installed when my attic was air sealed had expanded creating the 1/4" gap. I had that work done two years prior by Houle Insulation. I contacted Arne and inquired if he had any suggestions. His only suggestion was that he would correct the problem. Two days later he had two workers in my attic correcting the issue. Just like the first time, they were prompt and cleaned up after the work. I offered to pay, he would not have it. He said he should have noticed when the job was originally completed two years prior. There was no discussion or haggling, he simply said he would correct it. As impressed as I was with the lower energy bill, I was more impressed with how he and his team comported themselves. Also my house was more comfortable because the temperature was more uniform within my house. This year when we moved into our new house, built in 1992, the first thing I did was call Arne to air seal the attic. My choice of whom to hire for air sealing my attic was a no brainer, Houle Insulation. They also performed a blower door test. They also sent in all the information required for me to receive an energy rebate from my utility company. The best recommendation I can make is that when I decided to air seal our new home the first person I called was Arne. He made a wise decision to correct what needed with correcting without any questions. He did what should have been done, and therefore he got my repeat business and I was happy to give my business to him!"

"I recently had the pleasure of working with Koala Insulation of St. Paul for the installation of 4 inches of spray foam insulation in my garage attic, and I couldn't be more satisfied with the results. From the outset, Koala Insulation impressed me with their professionalism and expertise. Their team was punctual, arriving on time for the initial consultation and installation. They took the time to explain the benefits of spray foam insulation, including its superior air sealing properties and energy efficiency compared to traditional insulation materials. This thorough approach gave me confidence in my decision. On installation day, the crew was efficient and respectful of my home. They came fully prepared with all the necessary equipment, and I appreciated their attention to cleanliness. They took care to cover areas that needed protection, minimizing any mess during the installation process. The actual application of the spray foam was quick and straightforward, and the team worked collaboratively to ensure a high-quality finish. After the installation, the team provided useful guidance on maintaining the insulation and what to expect in terms of performance. They made themselves available for any follow-up questions, which shows their commitment to customer satisfaction even after the job was completed. I highly recommend Koala Insulation of St. Paul for anyone considering an insulation project, including upgrading or replacing your current fiberglass insulation. Their timely service, knowledgeable staff, and high-quality workmanship resulted in a seamless experience will undoubtedly improved my home's comfort and energy efficiency as we head into the cold season. If you're looking to enhance your insulation, look no further â Koala Insulation is a solid choice!"

"I was really impressed with the whole team at Guevara Insulation. They worked efficiently, the quality, and attention to detail was top notch. As a builder, and remodeler I've worked with many tradesmen over the years. So I can tell when guys really care about what they do, and it shows in their work. I had them work on my personal home build. They spray foamed all the exterior walls, and joist pockets, installed fiberglass batts, poly'd and caulked all framing seams. Then came back to finish the blow in once the drywall was up. I'll definitely be using them on my future projects, and will be recommending them to anyone needing insulation work done."

"Aaron was so helpful from the get go. We had two other attic insulation companies assess our issues when we had mold and water damage along the outside joists of the house. He was very knowledgeable and through and got the the causes of the issue. eRoof cleared out the plugged up soffets, sealed them, put in the needed baffling, and brought the blown in insulation up to the new code. Aaron had connections and we were able to get very efficient peers of his to do the mold removal, dry wall replacement, and painting. I would highly recommend this company and Aaron in particular. He was available to answer questions and help me think through this complex project."

FAQs for insulation service projects in Saint Paul, MN

Old insulation should be removed when it shows damage, contamination, or heavy deterioration. If you notice water stains, rodent droppings, mold, or large gaps, plan on taking it out to protect your home’s energy performance and indoor air quality. Removing compromised material eliminates health hazards, cuts energy loss, and sets the stage for a safer, more efficient attic—all while keeping utility bills in check.

R-value measures how well insulation resists heat flow—the higher the number, the better it slows heat transfer. The right R-value keeps your home warmer in winter and cooler in summer, saving energy year-round. Match the rating to your climate zone and have a pro verify performance over time, because moisture or settling can lower R-value and cut efficiency.

Attic insulation can stay in place for 80 to 100 years, but its performance often drops after the first 15. As dust, moisture, or mold build up, the material loses R-value and allows heat to escape. Schedule periodic inspections so a pro can tell you when replacement makes sense—helping you keep energy bills down and indoor comfort up.

You can over-insulate an attic. Beyond the recommended R-value, extra layers don’t add efficiency and can trap moisture, leading to mold or reduced performance. A local insulation pro can measure current levels, confirm the right target for your climate, and advise on any adjustments so you avoid future energy or maintenance headaches.

Insulation can be damaged by mold, pests, water leaks, or accidental electrical contact. When the material is compromised, it loses R-value and can introduce health hazards. Removing and replacing affected sections restores efficiency, while routine inspections from a qualified pro help you catch problems early and keep your attic safe and energy-smart.
